Unpacking, Assembly and Preparation

Warning

The engine must be thoroughly lubricated, and filled with fuel prior to break-in or use. Refer to manufactures instructions for details of service for the engine. The section on Maintenance in this manual describes the required periodic maintenance required under normal use.

Initial Servicing

engine preparation

add oil

The engine may be shipped with oil in the crank case. Check crankcase dipstick. To fill the crankcase with oil, place the engine level. In order for this to be accomplished the blade must not be installed, and the depth adjustment must be down (until the engine is level). Refer to the manufacturers instructions for details on the type and amount of oil required. Since the proper amount of oil is important for safe operation, check the oil level of the engine each time you put fuel in the gas tank. Remember that the engine and oil must be warm and your saw must be on level ground to get an accurate reading.

notice

Warning

add fuel

In the event of a fuel spill do not attempt to start the engine until the spilled fuel has been wiped up and the area is completely dry. When filling the fuel tank do not overfill. Always leave enough area for expansion due to environmental heating.

The engine is designed to operate on regular grade unleaded gasoline only. Adding fuel to the tank should be accomplished only when the engine is stopped and cool. Care should be taken to prevent spilling fuel over any part of the console or engine.

When mounting the blade, locate the direction arrow on the blade and install the blade in the proper orientation. The blade rotates clockwise when viewed from the right side of the saw.

The blade must be properly fitted over the blade shaft and drive pin. The drive pin must project through the hole in the blade and into the flange for proper performance. When tightening the blade shaft nut against the outside of the flange, tighten securely. Blade shaft threads are left-hand on the right side of the saw, and right-hand on the left of the saw.

DO NOT operate without the proper blade guard covering the blade! DO NOT operate the saw with the front of the blade guard raised. Ensure that blade exposure does not exceed 180 degrees during operation.

When installing the blade insure that the blade shaft and flanges are free of dirt and all foreign material before mounting blade on the arbor shaft. Tightening the blade against a uneven surface can cause fracture of an abrasive blade or cause the blade to run out of alignment, which will result in excessive blade wear. Before mounting the blade on the arbor shaft, check to be sure the shaft is not damaged and the threads are clear of dirt and residue.

The front pointer is set in line at the factory. However, the pointer should be checked for proper alignment with the blade after every use. The following are the procedures for aligning the pointer with the blade, with the engine shut off.

1. Using a straight edge, carefully mark a line 12 feet long on a smooth level concrete surface. 2. Place saw parallel to line. Lower blade and center it over the line. 3. With the blade centered over the line and the saw frame parallel to the line, lower the front pointer assembly and position the pointer over the line. 4. Finally, roll the saw along the entire length of the line. The saw should lead off no more than 6 inches to the left in 12 feet of forward travel. Adjust the pointer in or out if the lead-off is outside this parameter.

Raise the blade as high as possible when maneuvering so that the blade will not strike the pavement.

The blade is spinning whenever the saw is running.

maneuvering the sawnotice

Warning

Raise the blade as high as possible when maneuvering so that the blade will not strike the pavement.

The speed control lever for the hydrostatic transmission is adjusted at the factory to provide approximately 40 ft/min maximum in forward and 20 ft/min maximum in reverse with the engine running at full throttle. When maneuvering, the engine needs to be at one-half throttle or more so that the hydrostatic transmission can operate efficiently.

When the TRANSMISSION LEVER is in NEUTRAL and the DRIVE DISENGAGE LEVER is in the ENGAGE position, the transmission is in NEUTRAL and the wheels are locked.

To engage the transmission push the engaging lever down on the right rear of the console cowling. To disengage the transmission pull the engaging lever up. When the saw is manually pushed, the transmission must be disengaged. The transmission speed control lever is located on the top of the console. This lever controls the variable forward and reverse ground speed (up to 40 feet per minute) of the saw.

The water used on the blade is to provide coolant during cutting, and to flush the concrete cutting from the cut.

The water hose bibb is located below the throttle control on the left side of the saw. After connecting the water supply, turn on the water at the source and use water valve on console to control flow of water to blade. Be sure that both sides of the blade are getting adequate flow of water. The water control adjustment allows the operator to manually control the flow of water to the blade during all operations.

wet cutting

When engaging the transmission, with the engaging lever, be sure the speed control lever is at the neutral position to avoid saw movement.

Warning

dry cuttingDry cutting blades have been specially designed for use with concrete saws. Ensure that the blade you are using is clearly marked for dry cutting.

When dry cutting, it is important to keep the air filter clean. Check the condition of the filter at least every four (4) hours of operation. Clean the pre-filter (wash in soapy water and re-oil) and change the paper filter as soon as it becomes clogged. Concrete dust is very abrasive, and will quickly damage internal engine parts, causing loss of compression and eventual engine failure.

Saw only as deep as the specifications and job conditions require. Remember airflow helps to cool the blade during dry cutting. Cutting too deep with one pass, or exerting excessive forward or side pressure can be dangerous. Step cut in increments of 2 inches (50 mm) or less, for the best results.

If reinforced abrasive blades are used for cured concrete it is usually better to saw only 1” deep per pass if deeper cuts are required, cut in multiple passes.

Thinner Diamond Blades are especially advantageous when cutting dry.

aligning the saw with a marked lineRefer to the figure below. Push the saw forward and approach the marked line at an angle. Stop when the distance from the rear edge of the saw frame to the line (distance A) and the distance from the pointer to the line (distance B) are approximately equal. Lift the rear wheels slightly off the ground by lifting on the handles and swing the rear of the saw around until the pointer is on the line and the saw frame is parallel to it. Do not tilt the saw too far forward to keep the blade from contacting the concrete. The saw should now be aligned with the marked line. Practice will fine tune this method. Critical to this method of alignment is to ensure that the saw pointer is properly aligned (see alignment procedures).

With the engine running at half-throttle. Open the water valve to full open. Check to verify that the water is flowing fully. Adjust the amount of water flowing on the blade to a desired amount.

After adjusting the flow of water increase to proper throttle setting. Lower the blade into the cut by slowly turning clockwise on the depth control wheel. If the water supply is interrupted, stop cutting immediately.

When the desired depth of cut is reached, lock the control wheel in position with the depth control locking knob. During cutting, do not exert excessive side pressure on the handle bars to attempt to steer the saw. Use only enough pressure to follow the original marked line.

starting a cut

If the saw should stall for any reason, raise the blade out of the cut before restarting the engine!

When lowering the blade into a partially made cut, the blade must be perfectly aligned within the cut before starting to saw again. DO NOT force the blade into the material by lowering the blade too fast.

Warning

sawing a straight lineThe following items should be considered for best economy and efficiency in sawing:

With the water on, engine at the correct throttle setting, and the blade lowered, push the saw forward referring to the pointer alignment.

The saw has a natural tendency to pull towards the side on which the blade is mounted. To assure straight line cutting, apply pressure to the appropriate handle. If excessive pressure is required back off on the forward speed of the saw. If excessive pressure is still required to make the saw travel straight, the saw may need to have the arbor shaft adjusted.

Avoid sudden corrective actions when the saw deviates from the intended line of cutting. Sudden and severe corrections can cause the blade to be damaged or broken.

If the saw stalls in the cut, raise the blade out of the cut and check the blade shaft nut before restarting the engine.

Always raise the blade completely out of the cut before stopping the engine or turning off the water supply.

When sawing joints, be careful not to let the blade cut into the forms.

The forward speed of the saw, during cutting, should be regulated by the operator. Driving the saw too fast while cutting may cause the front wheels to lift causing the blade to cut at uneven depths.

The three controlling factors of cutting economy are:

1. Depth of cut

2. Forward speed of the saw (with the engine at proper throttle)

3. Blade cutting ability

Experimental adjustment of these items, with respect to the aggregate being cut will result in the best cutting economy.

As new blades wear, the cutting ability usually improves. It is best to start at a slow forward speed with a new Blade and work up to a desired cutting speed gradually.

Warning

10

Since diamond blades cut best at specific rim-speeds, blades of different diameters must be turned at different blade shaft rpm’s.

The PA2013HSP will run either a 14 or 18” blade and the PA2020HSP will run a 16” through 20” blade.

Safe, efficient, economical cutting performance will occur at the engine rpm (as read on the tachometer) stipulated on the following chart.

Operating saw blades at rotational speeds greater than those recommended by the manufacturer can cause blade damage and possibly subsequent personal injury.

Never exceed 3600 rpm blade shaft speed.

* The PA2013HSP Series, it is possible to cause overspeeding of the blade at throttle settings above those stipulated on the above chart; DO NOT EXCEED THESE ENGINE RPM SETTINGS!

The PA20 Series engine shaft to blade shaft ratio is 1:.895.

Raise the blade out of the cut by cranking the depth control wheel counter-clockwise. Raise the blade high enough out of the cut to clear the pavement and allow maneuvering of the saw.

Move the engine throttle to the slow position then turn the kill switch off.

Turn off the water valve.

finishing a cut

cutting with the blade on the left sideLeft side cutting can be easily accomplished by moving the blade guard to the left hand side of the saw belt guard using the following steps:

1. Turn kill switch to off position.

2. Disconnect water hose from blade guard.

3. Remove shaft guard, from the left side of the saw frame and set aside.

4. Remove blade guard from the right side of the saw frame and reassemble on the left side of the saw belt guard.

5. Reassemble shaft guard on the right side of the saw frame.

6. Connect water hose to blade guard.

When attaching a blade to the left blade shaft, use the outside flange from the right side and the left side nut.

Do not operate saw with any guards removed. Turn kill switch to off position to avoid accidental starts when removing guards.

Warning

11

Shut off the engine before performing any maintenance. If the engine must be run after a maintenance operation make sure the area is well ventilated. The exhaust contains poisonous carbon monoxide gas! Exposure can cause loss of consciousness and may result in death.

MaintenancePeriodic maintenance including cleaning, lubrication, tensioning of drive belts, and inspection for wear and damage are routine servicing procedures. Following the procedures as outlined in the following table can prevent serious damage or malfunctioning of the machine and aid in preserving the useful life of saw blades.

friction drive wheels adjustmentIf the friction drive wheels DO NOT engage the rear wheels with sufficient pressure, slippage of the rear wheels may occur. To correct this situation, lengthen the engagement linkage by loosening the two (2) linkage adjustment bolts. Lengthen the linkage bars a small amount and retighten the bolts.

controls

grease points

Stiff or sluggish response of controls must be corrected immediately. Periodically clean and lubricate the throttle cable, the throttle and choke controls. The frequency of this maintenance will depend on the utilization rate and the amount of dust. After performing any maintenance on controls, saw responsiveness must be checked before the initiation of sawing operations.

There are four (4) grease points (zerk fittings) on the PA20HSP Series concrete saw.The blade shaft bearing grease points need to be serviced at the end of operations on a daily basis. The rest of the grease points require service on a weekly basis (see maintenance schedule). The two blade shaft grease points are accessed from underneath by tilting the saw back. The raise/lower adjustment tube grease point is accessed from the inside of tower control box. The transmission drive spline shaft bearings are accessed from the inside of tower control box and by raising the front of the saw to access from underneath the frame. See parts lists for grease point locations.

hydrostatic transmissionThe hydrostatic transmission should not normally require maintenance. However, the hydraulic oil level in the reservoir and the cooling fan blade must be checked frequently.

drive chainChain tension is adjusted by loosening the four transmission bracket mounting bolts and moving the transmission up or down as required. All nuts must be retightened after each adjustment. Excessive tension on the drive chains will reduce chain life and should be avoided. Periodically wipe the chain clean and relubricate with penetrating chain lubricant.

Breakage of the drive chain will result in the loss of braking friction through the drive wheels. Perform daily checks of the drive chain. If any damage is noted the chain must be replaced.

Caution

neutral adjustmentIf, due to transmission control cable or other component replacement, the transmission control system needs to be adjusted to obtain NEUTRAL the following procedure must be followed:

1. Stop the engine and Place Drive Disengage Lever in Disengage position.2. Remove the belt guard. Loosen the engine mounting bolts, remove the v-belts and slide the engine as far forward as possible (approximately 2”).3. Loosen cable clamp on transmission control arm.4. Place Transmission Speed Control lever in neutral.5. Place the transmission in neutral by moving the transmission control arm back and forth while manually rotating the transmission pulley. When the pulley spins freely and no movement of the drive chain is observed, the neutral position has been obtained.6. Tighten the cable clamp.7. Replace the v-belts and properly adjust v-belt tension by repositioning engine and tightening the mounting bolts.8. Reinstall the belt guard.

13

notice

v-belts This machine is equipped with two heavy duty V-belts which are tensioned properly at the factory. These must be re-tensioned after the first half day of operation and periodically thereafter. Adjust to the original tension as set at the factory, which is approximately 1/4 inch of defection of the center of the belt halfway between the pulley on the motor and the pulley on the blade shaft.

To adjust belt tension, first remove the belt guard. With the belt guard removed, loosen motor mount bolts. Loosen the lock nut and adjust set bolt on the motor tension adjuster until the required belt tension is achieved.Retighten the motor mounting bolts.

The two most common causes of misalignment are shown in the drawings.a). the engine drive shaft and the blade shaft are not parallel.b). the pulleys are not located properly on the shafts.FIGURE TWO

FIGURE ONE

electrical systemA fuse protects the battery charging circuit. The fuse and the battery are the only user serviceable parts of the electrical system. a short circuit or a battery connected in reverse polarity will blow the fuse. Refer to the Honda engine manual for the location and type of fuse. The fuse on the Honda engine is located between the starter solenoid and the engine, and is rated at 30 amps.

If the fuse blows, determine the cause of the problem before resuming operations.

Caution

Check water level weekly. Add distilled water if necessary. Check terminal cables and remove any deposits. Remove the battery for recharging and follow the instructions for recharging. Damage can result to the battery and electrical system if the battery is charged or installed in reverse polarity. Make sure that the negative terminal is connected to ground. Remove and install battery as per instructions in initial servicing section of this manual. Be careful not to contact metal while loosening positive terminal with tools.

Observe all battery precautions as outlined in the Initial Servicing section of this manual.

Caution

depth control

water system

The depth control (raising screw) consists of a threaded rod which feeds into a steel nut. In order to keep the two parts working smoothly it is necessary to keep the rod free from dirt and sludge as much as possible. Cleaning the threaded rod with a rag after each use will prevent sludge from collecting in the tube assembly and protect the threads. It is a good practice to keep the raising screw threads lubricated, as the slurry generated during cutting will cause premature thread wear.

Check and clean system periodically. Make sure all outlets in the blade guard spray bars are open. Clean if necessary. When storing saw under freezing conditions it is recommended that the water lines be drained to prevent damage.

Note: gap between steel straight edge and sheave

Never make adjustments to belts or pulleys while engine is running.

DO NOT OVER TENSION as damage to belts and bearings may occur. Belts that are too loose may slip, resulting in short life and loss of power to the blade shaft. If any belts are worn or damaged, replace the complete set.The motor mounting plate must be maintained parallel to the frame. Make sure all lock nuts are tightened and retighten the bracket bolts.See parts list for further v- belt spec. information.
